Maintaining thermal comfort and mitigating heat stress requires a comprehensive approach encompassing both indoor and outdoor environments. Indoor monitoring systems, utilizing sensors and data loggers, track temperature, humidity, and air quality to optimize HVAC systems and ensure occupant well-being. Outdoors, monitoring stations employ weather sensors, wearable technology, and mobile apps, crucially including WBGT (Wet Bulb Globe Temperature) sensors, to track heat stress indices, enabling timely interventions like hydration breaks and work schedule adjustments to protect individuals from heat-related illnesses. Integrating indoor and outdoor data, including WBGT readings, provides a holistic view, allowing for proactive adjustments to building systems and work practices based on real-time conditions. This integrated approach is crucial for enhancing safety, productivity, and overall well-being in the face of increasingly extreme temperatures.
